for small scale applications. It has 8 inputs and 6 outputs. It has a 24v input slot which acts as a power source for delta plc. It also has a USB slot which is used to run the program on the plc. A very commonly used method of programming PLC’s is based on the use of ladder diagrams. Writing a program is the equivalent to drawing a switching circuit. The ladder diagram consists of two vertical lines representing the power rails. Circu its are connected as horizontal lines, that is, the rungs of 1|P a ge
